IPC: H04N11/04
Filed: 1989-10-13
Abstract: PURPOSE:To attain reproduction up to the same frequency as a sampling clock by operating two A/D converters in the sampling clocks of opposite phase in the case of the operation in the double density mode. CONSTITUTION:An analog composite video signal is inputted to an A/D converter 2 and a switch circuit 1 is passed with a switching signal (a) in the case of the double density mode and the video signal is inputted to a 2nd A/D converter 3. Thus, the 1st A/D converter 2 and the 2nd A/D converter 3 are operated by the sampling clocks of opposite phase. Moreover, the output of a 1st multiplexer circuit 4 is inputted to a high pass filter circuit 8, which is operated by a clock twice the sampling clock and a high frequency component being 1/2 of the sampling clock or over is passed therethrough. Thus, the signal of up to the same frequency as the sampling clock frequency is reproduced.

Title: Testing method for magnetic recording medium and magnetization time constant measuring method for magnetic piece
Inventor: BABA YASUO
IPC: G11B5/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To correctly evaluate the recording life of bits comforming with a magnetic recording medium by recording recording patterns having a difference in the sum of + bit and -bit areas on a magnetic recording medium with a prescribed recording density and measuring residual magnetizations with time. SOLUTION: A first recording pattern area 1a where bits are uniformly magnetized and and second and third recording pattern areas 1b, 1c where a recording density is a recording density to be measured and + bit and - bits are ununiform and magnetization inversion densities are different are formed on a magnetic recording medium 1. Rectangular test samples 2a, 2b, 2c are cut out from respective areas 1a, 1b, 1c and characteristics of residual magnetizations with respect to the elapsed time and inclinations with respect to the time train are calculated from averages of inclinations of prescribed number of measurement points. Next, rates of contraction and lieves concerned with a thermally fluctuated magnetic relaxation are evaluated by calculating magnetization inversion time constants with respect to the elapsed time.  Thus, the extracting of parameters of physical properties concerning magnetic particles of respective bits is made possible by limiting recording patterns to a bit constitution consisting of two kinds of magnetization quantities and the direction of magnetization in this manner.

Title: Method and device for communication network security using invalid symbol security interference
Inventor: MICHAEL A SOKORU
IPC: H04L12/24
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a security device used in a communication network device, such as a multi-port repeater. SOLUTION: This security device prevents wire tapping in a local area network, by overwriting data with an invalid symbol in all data communication packets transmitted to all unspecified transceivers. Since the invalid symbol is defined independently on the data, information which is confidential or for which caution against a user is required will not be transferred to the unspecified transceivers. The invalid symbol clearly informs the unspecified transceiver of the fact that the data in the data packet are invalid.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: KADOWAKI HISASHI
IPC: F02D41/14
Filed: 1992-10-06
Abstract: PURPOSE:To realize highly accurate lean control by identifying a misfire limit exactly without being influenced by an individual difference of an internal combustion engine. CONSTITUTION:When lean control is carried out, average deviation M.Dl=1 of a difference in angular velocity learned at the time of a theoretical air-fuel ratio (l) = (1) is subtracted from average deviation M.DL of a difference in present angular velocity generated in an internal combustion engine, and a fuel injection quantity is corrected according to equivalence DELTAM.D of an obtained misfire increase. Thereby, since the average deviation M.Dl= 1 at the time of the theroretical air-fuel ratio (l):(1) changing according to an individual difference of an internal combustion engine is excluded, a air-fuel ratio is controlled according to only the equivalence DELTAM.D of a misfire increase caused by a misfire, so that a misfire limit can be identified exactly without being influenced by the individual difference of the internal combustion engine.

Title: Remote control relay
Inventor: YOKOYAMA YOICHI
IPC: H01H51/24
Filed: 1988-10-24
Abstract: PURPOSE:To enhance the endurance for eventual shortcircuiting current or any other overcurrent by allowing such current to flow divergently to a contact spring and a flexible conductor. CONSTITUTION:A flexible conductor 13 is furnished in parallel with a contact spring 14 of a main contact block B, and current is allowed to flow divergently to the contact spring 14 and flexible conductor 13 in case a large current flows such as shortcircuiting current or any other overcurrent.

Title: Device and method for treating wafer
Inventor: SHIBATA AKIHIRO
IPC: H01L21/304
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a wafer treating technique which can stabilize quality of wafer treatment and prevent delays in wafer treatment. SOLUTION: A pressure sensor is provided in a wafer treatment chamber. When pressure is reduced in this wafer treatment chamber, elapsed time is measured after decompression is started, that is, a decompressing pump is activated. If a pressure Pa detected by the pressure sensor reaches a target decompression value Pr before the elapsed time reaches a prescribed abnormality threshold time Ts, normal decompression state is determined, and the pressure is reduced by the decompressing pump until a decompression step time Tv elapsed. However, if the elapsed time reaches a prescribed abnormality threshold time Ts before a pressure Pb reaches the target decompression value Pr, abnormal decompression state is determined, and an abnormal message is displayed on a display and abnormal processing, such as stopping the decompressing pump or the like is performed.  As a result, quality of wafer treatment can be stabilized by checking the decompression state by the pressure sensor and delay of wafer treatment can be prevented by abnormal processing, in the case of abnormal decompression.
